TXMC Polypropylene staple fiber is used to manufacture Air Filter, Water filter and other industrial fabric, It is also used for woven carpets, non-woven carpets, upholstery, carpet backing etc. 

Polypropylene staple fibers offers superior feature due to its lowest specific gravity resulting into better relative coverage, high dimensional stability, excellent recovery properties namely elasticity and resiliency, low thermal conductivity, lowest static charge and its inertness to chemicals. 

The denier of PP Fiber manufactured is 1.5D to 15Denier.

Process of PP One Step Fiber Production Line

Polypropylene fiber is manufactured from isotactic polypropylene chips by melt spinning process. In this process molten polymer from a manifold is metered through various spinnerets, having number of holes to form filaments. These filaments/fibers are then solidified by air/water quenching and after application of spin finish are directly to draw line part in one step process. The fiber is stretched several times in a chemical hot bath, relaxed and crimped to be made suitable for various spinning systems.

Applications of Virgin Polypropylene Staple Fiber

Spinning Yarns, Filter Fabrics, GeoTextile, Auto-mobiles floor carpet, thermal bonded fabrics, insulations, carpet, and non-woven carpet, building construction, RCC

Polypropylene staple fiber is also available in short cut length for RCC building construction and making cement sheets, tiles and pipes. This enhances strength of the cement/RCC. Fiber Reinforced Concrete (FRC) is Portland cement concrete reinforced with thousands of small fibers more or less randomly distributed during mixing and thus improve concrete properties in all directions. Polypropylene fibers of 0.5% to 1% are normally used in concrete. Natural white polypropylene fibers of 3 and 6 Deniers and in lengths of 6, 12 and 20mm respectively are commonly used in various applications.
